Spring insight what just happened
- 1. Spring Insight – What Just Happened? Derek Beauregard
- 2. Agenda • What Just Happened? – Agile Development, QA, Stress & Performance tesCng – Logging? – Debugger? • STS & Integrated in Tomcat (tc Server) • Spring Insight Demo Time • JMeter & Google Chrome Speed Tracer • How it works • Plugins & AnnotaCons • Wrap up
- 3. Who is this guy?
- 4. Contact Info • Derek Beauregard – Sr. Field Engineer, Pivotal (formerly VMware & formerly Spring Source) – [email protected] – goPivotal.com – vfabric.co
- 5. My Fancy New Web ApplicaCon
- 6. ApplicaCon Development & TesCng • So your building your fancy new web applicaCon – Is it working the way you expected? – What caused that failure? – How is the performance? – Why is it slow? – What the heck is Hibernate (or whatever) doing?
- 7. My Fancy New Web ApplicaCon
- 8. What do you do when it fails? • Check the logs? – Timestamps – Session IDs, User IDs – Log all the parameters – UGH? • Run the debugger? – Typically doesn’t help with performance • And what do you do in QA and Performance TesCng? When it fails? When it is slow?
- 13. There has got to be a beXer way! • Spring Insight!
- 14. BETTER WAY
- 15. Demo
- 27. Web ApplicaCon Spring Insight Client (Browser, JMeter, etc.) Web Layer Service Layer Data Layer DB Spring Insight Messaging Caching
- 28. How does it work? • Spring Insight uses automaCc code instrumentaCon to monitor your applicaCon • It does this by introspecCng exisCng annotaCons and interfaces for key aspects of your applicaCon • It then uses AspectJ AOP point cuts to monitor the code • Runs in tc Server (Tomcat) beside your web applicaCon
- 29. Plugins Custom… Spring Integra;on
- 30. More Plugins • AnnotaCons • Akka • Axion • BlazeDS • Cassandra • Eclipse-‐Persistence • Ehcache • Ejb3 • Files-‐tracker • GemFire • Grails • Hadoop • Hibernate • HXpClient3/4 • jax-‐rs • Jcr • JDBC • JMS • JMX • JNDI • Jolt • JPA • JTA • JWS • LDAP • Logging • Mail • MongoDB • Portlet • Quartz • RabbitMQ • Redis • RMI • Run-‐exec • Servlet • Socket • Spring-‐Batch • Spring-‐Core • Spring-‐Data • Spring-‐IntegraCon • Spring-‐Neo4j • Spring-‐Security • Spring-‐tx • Spring-‐web • Spring-‐WebFlow • Struts2 • Tomcat • Developer Kit & GitHub
- 31. Plugins • Many plugins are supported out of the box • You can get more from GitHub or develop your own using the Developer Kit • GitHub: hXps://github.com/SpringSource/spring-‐ insight-‐plugins

- 33. AnnotaCons • If you want to monitor more aspects of your code you can simply annotate the methods
- 34. Dynamic Concrete Aspects <?xml version="1.0" encoding="UTF-‐8"?> <aspectj> <aspects> <concrete-‐aspect name="foo.bar.BazAspect” extends="com.springsource.insight.collecCon.method.custom.CustomConcre CzedOperaConCollecConAspect"> <pointcut name="collecConPoint" expression="execu;on(* foo.bar.Baz.mySuperDuperMethod(..))" /> </concrete-‐aspect> </aspects> </aspectj>
- 35. Dynamic Concrete Aspects • Instrument classes and methods that are not covered by plugins or Insight annotaCons • Defined in AspectJ XML configuraCon • No changes to source code required!
- 36. Spring Insight • AutomaCc • No Coding & No ConfiguraCon • Shows Errors • Shows Performance • Pluggable • Answers: “What Just Happened?”
- 37. Wrap Up • Helps developers, QA Testers, and in Stress and Performance tesCng to answer: “What Just Happened?”
